Another year passed by

Birthdays were celebrating by the killers. At first, they didn't celebrate Tsuna's birthday because they didn't know her birthday. Then, they had learned about her birthday and started celebrating it. Basically, she was celebrating her fifteenth birthday with the four killers, and two more killers.

"I don't fuckin' care what you think." A man with pale skin and carved smile said entering the house they were living in. Tsuna recognized immediately the man, she had met him years ago. He had let her because she was a proxy. He wasn't alone, he was followed by a young woman wearing a black hoodie. Her hood was hiding her face. "Bitch."

The other proxy – Tsuna saw the marks on her (several, she noticed – stayed silent. She didn't say anything. The killer noticed it too and smirked. He turned his head towards Jason, the Toymaker was leaning against the wall amused. The young woman – who didn't seem to age – revealed her face as soon as the killer ordered it. She had dirty black hair, her skin was almost grey for some unknown reason, she had a scar across her neck and another across her right cheek. A smell of blood, sweat, and dirt came of her. Jason leant towards the proxy who didn't move nor flinch as he looked the marks.

"You, and the clone of Link ?" Jason chuckled guessing each mark.

"Ben ? No. Not him. Definitely not him. The last mark is that damn cannibal." Jeff said throwing an arm around his proxy's head.

Soon the killers left the hall. Tsuna was left alone with the other girl. The girl sighed quietly used to that sort of event. She turned her head towards the other proxy.

"I'm Tsuna. Or sometimes they call me Ash." Tsuna introduced herself feeling she had to speak first.

For a long moment, she got no reply. Then, ten minutes later, the other proxy finally spoke. "Wolf."

Tsuna threw her a confused look and Wolf clarified. "My name. Don't remember exactly my name."

Tsuna nodded. She led Wolf to another room hearing the killers speaking inside of the kitchen.

"You're fuckin' young, ain't ya ?" Wolf asked quietly as she walked inside of the house.

"I'm fifteen." Tsuna said. "You look young, but not at the same time." She added.

"Eh. Yeah, it's quite normal you know. It's been a very long time since I became a proxy. My age doesn't matter anymore, but Jeff likes to remain me all the damn time." Wolf admitted pulling out a knife.

She sighed again. Obviously she looked bored to death. Tsuna watched as the knife began to twitch in her hands. Tsuna didn't really kill as much the others did. Wolf was completely different. Her intention of kill was rising slowly, her call of blood was clear as water.

"I need to kill. The itch is back, fuck." Wolf mumbled to herself.

"Itch ?" Tsuna asked curious.

"You know, that damn itch which hurts you so much until you finally kill ? I've it now. I kill the last time. But it's been long enough for me to have to kill again."

Tsuna wanted to reply something, but the killers came into the room. Jeff's gaze fell on Wolf, her eyes were staring at the wall, her knife was twitching. Jason and the twins sat on the couch, Puppeteer took Tsuna's arm and began to walk out. Wolf was following them with Jeff close to her. The duo was moving silently and mortally through the night, it was too dim to see anything, but Tsuna could say they were following the duo.

"They're perfect, ain't they ?" Jeff chuckled darkly huffing tightly his proxy. He pressed his knife on her throat, he could feel her envy of kill. He wanted blood, he wanted her to annihilated many people she could, he wanted her to do so many dark things. He smirked releasing slowly the girl.

"Kill every single one of them. Slit, rip, tear up their throat, their stomach, lick and drink their blood for me." He whispered in her right ear.

The itch was crazy. She could not stand it anymore. Wolf walked to the house, the door wasn't even closed so it was easy for walk in. Someone screamed. Wolf didn't care, a crazy smile appeared on her face as she jumped on the first person she saw. People started to scream, someone tried to hurt her, but she threw herself on him stabbing him violently in the stomach. One by one, they fell under her knife. Blood spread on the carpet, the ground, Wolf's clothes, Wolf's skin, people's skin and people's clothes. The itch was almost gone. She continued to stab until she rip every body in lamb. She licked the blood drinking it for Jeff as he had instructed.

Wolf stood up. Tsuna was silent, her eyes widened to the bloody living room where dead bodies laid down. Puppeteer chuckled, he had appreciated the entire show of Jeff's proxy. He glanced at Tsuna seeing her shock on her face. He hoped to see her doing the same thing later. Maybe in the future years, he thought to himself smirking. He wanted her to see Wolf – an old proxy – in her most crazy moment. If she were going to see Wolf more and more – it was likely – she needed to understand that Wolf was different from her. Old enough to understand how a proxy evolved and what a proxy became. And she would actually have a real friend.

But he was looking forward to see her on killing spree like this. He smirked. He would enjoy it to his best.

Tsuna saw Jeff removing his pants. Her eyes widened as she realized what he was going to. But Wolf seemed relaxed. She noticed Jeff's behavior, however she did nothing. She wasn't worried, Tsuna noticed wanting to tell her what he was going to. She was worried for someone she hadn't know for long, Puppeteer grabbed her hand and pulled her out of the path. The man with yellow eyes had a strange look. As Jeff grabbed his proxy, Puppeteer disappeared with Tsuna leaving Jeff and his proxy doing whatever they wanted.

Jeff smirked. He liked to have sex with his proxy. Wolf didn't mind at all. It was literally a stress reliever for her. It was quite normal for both to have sex after a killing spree.

"She won't know that." He mumbled to himself thinking about the young girl.

Because the four killers chose to use other people to satisfy their sexual desires. Thus, the girl was young, he thought. However, some killers didn't care about age.

Reborn felt weak. He never felt so weak like this. His body was sore. His back was hurting like hell. His clothes were stained by blood. His flames were barely healing him. He hated so much Checkerface, the man was torturing him for months now. He had tried to apologize only to be slap to the face. He had tried to flee once, but one of Checkerface's subordinate had caught him and tortured him until he couldn't stay conscious. Reborn had wondered that time if he were going to die. Obviously no. Because Checkerface wanted him to hurt him even more. The job he had failed… he thought bitter. The girl who was going to be Vongola Decimo was above everybody, stuck to be someone's servant. He didn't understand it. She was a fuckin' sky, or was she ? He began to doubt all he knew. The girl was a killer, not a hitman or even an assassin who worked on contacts, but a true killer who killed everybody on her way.

"Shit."

He couldn't move properly. His right leg was broken. He was chained up to the wall barely breathing normally. He saw the door open on Checkerface, the man with an iron hat walked in.

"Awake ? I'm sure you're dying to know when I'll release you. Is that right ?"

Reborn didn't answer.

"Oh ? Playing deaf ? Or mute ?" Checkerface chuckled darkly approaching slowly his prisoner.

Reborn didn't speak.

"Right.. I'm here for something my dear Reborn. You're going to suffer again. For a month only. At the end of this month, I'll release you in the wild. Free to the other Arcobaleno to find you. Your flames will be sealed, out of your reach, they won't heal you when you'll be out. I still need you alive. I don't like you. You've been so arrogant. Even when you were not a Arcobaleno. You're not the only arrogant Arcobaleno. But you're the worst. Always bullying the weaker. My, my you're quite a bully. But my dear Reborn, I don't care about those you bully. However, Skull is my favorite."

Reborn gasped staring at the man. "W.. What ? What are you talking about ?"

The atmosphere was tense. Chains were attached to the walls, blood was dry on the ground. There was a table in the opposite of Reborn. Dirty and blood stained tools were aligned on this table. Checkerface was a tall man, mysterious, and so dark. Reborn shivered feeling the intention of kill rising in the room.

"Skull is my favorite. Do you have not heard that ? He's immortal after all." Checkerface smirked looking to the face of the sun Arcobaleno.

"You're fuckin' lying. And that damn lackey is not." Reborn protested finding the force to fight against the chains.

"Lackey ? Skull ? Oh my my.. You're really stupid. Maybe I should.. Nah. You're not worthy. However, when I'll kill you, I'll show you who is really Skull."

Reborn shivered. He didn't like the dark tone Checkerface had took.

"Now, sleep."

Reborn was suddenly sleepy. He didn't want to go to sleep.

"Fuck.. " He swore trying to fight the sleep.

"Sweet dreams." Checkerface bent over him smirking.

The world of Reborn went black after that.

Tsuna was walking behind the twins, Jason, and Puppeteer following them as they went to an abandoned building. Puppeteer had kidnapped several men, he had put every single one of them in a room unconscious. With Jason who gave him names of people to kidnap, he had organized a game. The twins had recruited several killers to play the game. Among them, there was Jeff the Killer. He had been staying with his proxy to their home until yesterday, they had left before them to the abandoned building.

"There is that damn bitch.. I can't wait to chase around." Puppeteer mumbled to himself, but enough loud to the others to understand what he said.

"How many chasers do we have ?" Candy Pop asked to the group.

Tsuna stayed silent. She hadn't knew about the project for weeks, they had kept it silent until it was ready.

"3." Jason replied quietly.

He was leading the group to the building. Tsuna noticed Wolf leaning against a stone pillar. She was wearing her usual black hoodie, her hood was hiding her face and hair. The killer was guarding the entrance. There were two stone pillars, the portal in metal was wide open despite the fact the proxy was guarding it. As they approached, Tsuna felt the presence of someone else. Someone appeared in front of the other stone pillar, Tsuna tensed not recognizing the boy. He was young, he had blue hair – what ? – and green eyes. He wore green pants, a grey shirt and a blue jacket sleeveless.

"Jeff's proxy and Ben's proxy." Candy Cane informed them as they stopped meters away from the two proxy.

Ben ? Tsuna thought trying to remember where she had heard this name. Ben's proxy glanced at Jeff's proxy then at them. Suddenly, both proxies disappearing. They appeared away next to the doors of the building. Tsuna noticed a strange sign, it read :

WEL OME TO T E HE L CE T R !

Welcome to the hell center, she understood after a few minutes.

They walked inside the yard. Tsuna was the last to enter, she was less reassured about the building. She caught up with the group, the killers were walking fast. She glanced behind her shoulder seeing the portal closing by itself. She blinked.

Yep. The portal really closed with nobody around. She blinked again.

Weird, she thought.

Wolf and the mysterious boy were waiting for them. The two proxies were good to disappear every time they got closer. Tsuna decided to pay attention to what the killers were saying while watching around her.

" – are chasing anyway ?" Candy Pop asked absently.

"The proxies." Puppeteer answered turning to the right.

"Jeff and Ben are already in the control room. The game is starting tomorrow morning."

The teen rubbed her hands. Great, she was a chaser. She had thought she could use this game to rest.

But no.

She noticed Wolf laughing silently at her. She must have know what she was thinking, the boy was smiling. The proxies were standing at the feet of the stairs. Once they entered the immense room where there were the stairs. The proxies went upstairs joining Ben and Jeff to the control room. The group arrived two minutes later.

End of the chapter.
